AMICIST Sounding Rocket Launch |
AMICIST (NASA/Arnoldy/U of NH Plasma Physics Flight 40.007) is a Black
Brant XII (typical Black Brant XII, 165k)
instrumented to measure the transverse acceleraton of ions due to a
nighttime aurora. The PI is Roger Arnoldy ; Co-I's are Kintner and Kelley
at Cornell U., Roy Torbert at UNH, and Tom Hallinan at the Geophysical
Institute, U. of Alaska. An earlier flight to study the transverse
acceleration of ions due to aurora discovered that it occurred in very
small structu res, 100 m across B, and an unknown length along B. AMICIST
is a two payload mission to try to separate space/time variations. It
will measure the distribution funtion of the auroral electrons and ions
(oxygen and hydrogen), and the frequency and wavelen gth spectra of waves
which in the earlier flight appeared to become very strong in the small
"caviton" structures. The mission is an attempt to study the microphysics
of this acceleration of ions which can be a universal phenomenon. The use
of multiple pitch-angle imaging detectors, very high telemetry rates on a
vehicle moving much slower than orbiting spacecraft make such a mission
unique. The Hallinan experiement is a narrow field of view photometry
measurement of the aurora below rocket apogee.
The launch window is Feb 25-Mar 30, 1995. It is planned to use near real time magnetic field and solar wind data from the WIND spacecraft to support this launch. |
